To be fair she does think that you're her killer. Compared to Glamrock Freddy she's done more good, everything she's done was what she thought was right
Okay first off, why the hell is Gregory on this list. That child is the complete opposite of pure. and second off, most of the characters on this list have no problem with killing and will try and kill you. Glamrock Freddy is the only one who doesn't want to kill the protagonist on this poll (Not counting prototype freddy because it's not confirmed that he's glamrock freddy)
Pretty sure Glamrock Freddy is the purest one on this list. I would say puppet, but she didn't need any corruption to murder you, and even admits she is aware, and human in the mind, unlike all the others.
